Hi,

  <%= @teaching.user.name %> has just changed the notes on a file<%= @upload.deadline.nil? ? '' : " for deadline \"#{@upload.deadline.title}\"" %> in the group <%= @group.name %>.

You can see the file at:
<%= "http://#{@host}#{upload_path(@teaching.project_id, @teaching.id, @group.id, @upload.id)}" %>
